Our privacy policy is intended to be simple and understandable for everyone. In this privacy policy, the official terms of the General Data Protection Regulation (DSGVO) are generally used. The official definitions are explained in Art. 4 DSGVO.

Access to and storage of information in terminal equipment

By using our website, information (e.g. IP address) may be accessed or stored (e.g. cookies) in your terminal equipment. This access or storage may involve further processing of personal data within the meaning of the GDPR.

In cases where such access to information or such storage of information is absolutely necessary for the technically error-free provision of our services, this is done on the basis of Section 25 (1) Sentence 1, (2) No. 2 TTDSG.

In cases where such a process serves other purposes (e.g. the needs-based design of our website), this will only be carried out on the basis of Section 25 (1) TTDSG with your consent in accordance with Article 6 (1) a DSGVO. The consent can be revoked at any time for the future.

For more information on the processing of your personal data and the relevant legal basis in this context, please refer to the following sections on the specific processing activities on our website.

Web hosting

This website is hosted by an external service provider (Scaleway). The hosting of this website takes place in the Netherlands. Personal data collected on this website is stored on the hoster’s servers. This may include, but is not limited to, IP addresses, contact requests, meta and communication data, web page accesses and other data generated via a website.

We have concluded an order processing contract with the provider in accordance with the requirements of Art. 28 DSGVO, in which we oblige the provider to protect our customers’ data and not to pass it on to third parties.

Server log files

When you call up our website, it is technically necessary for data to be transmitted to our web server via your internet browser. The following data is recorded during an ongoing connection for communication between your internet browser and our web server:

  • Date and time of the request
  • Name of the requested file
  • Page from which the file was requested
  • Access status
  • Web browser and operating system used
  • (Complete) IP address of the requesting computer
  • Amount of data transferred

We collect the listed data to ensure a smooth connection setup of the website and to enable a comfortable use of our website by the users. In addition, the log file serves the evaluation of system security and stability as well as administrative purposes. The legal basis for the temporary storage of the data or the log files is Art. 6 para. 1 lit. f DSGVO.
For reasons of technical security, in particular to defend against attempted attacks on our web server, we store this data for a short time. On the basis of this data, it is not possible for us to draw conclusions about individual persons. After 30 days
at the latest, the data is anonymised by shortening the IP address at domain level, so that it is no longer possible to establish a link to the individual user.
In addition, the data is processed in anonymous form for statistical purposes, if necessary. This data is never stored together with other personal data of the user, compared with other data or passed on to third parties.


Our website uses so-called “cookies”. Cookies are small text files that are stored either temporarily for the duration of a session (session cookies) or permanently (permanent cookies) on your terminal device. Session cookies are automatically deleted at the end of your visit. Permanent cookies remain stored on your terminal device until you delete them yourself or an automatic solution is provided by your web browser.

Cookies have various functions. Many cookies are technically necessary, as certain website functions would not work without them (e.g. the shopping cart function or language settings). Other cookies are used to evaluate user behaviour or to display advertising.

Technically necessary cookies are stored on the basis of Art. 6 (1) lit. f DSGVO. We have a legitimate interest in storing cookies for the technically error-free and optimized provision of our services. Other cookies are only stored with your consent on the basis of Art. 6 para. 1 lit. a DSGVO. The consent can be revoked at any time for the future. The legal basis may also arise from Art. 6 (1) lit. b DSGVO if the processing is necessary for the performance of a contract to which the data subject is a party, or for the performance of pre-contractual measures that are carried out at the request of the data subject.

If cookies are used for analysis purposes, we will inform you about this separately within the framework of this data protection declaration and obtain your consent.

EQS Newsletter

If you would like to receive the newsletter offered on the website with regular information about our offers and products, we require your e-mail as mandatory information. Additional data may be required in order to address you personally in the newsletter and/or to identify you if you wish to exercise your rights as a data subject.

We use the so-called double opt-in procedure for sending the newsletter. This means that we will only send you our newsletter by e-mail if you have expressly confirmed that you consent to the sending of newsletters. In the first step, you will receive an e-mail with a link that you can use to confirm that you, as the owner of the corresponding e-mail address, want to receive newsletters in the future. With the confirmation, you give us your consent in accordance with Art. 6 para. 1 lit. a DSGVO that we may use your personal data for the purpose of sending the desired newsletter.

When registering for the newsletter, we store, in addition to the e-mail address required for sending, the IP address through which you registered for the newsletter, as well as the date and time of registration and confirmation, in order to be able to track possible misuse at a later date.

You can unsubscribe from the newsletter at any time via the link included in each newsletter or by sending an e-mail to the responsible person named above. After unsubscribing, your e-mail address will be deleted from our newsletter distribution list immediately, unless you have expressly consented to the continued use of the collected data or the continued processing is otherwise permitted by law.

Our e-mail newsletters are sent via a technical service provider to whom we pass on the data you provided when registering for the newsletter. We have entered into an order processing agreement with our email service provider, in which we oblige them to protect our customers’ data and not to pass it on to third parties.

Service provider: EQS Group AG

Karlstrasse 47
D-80333 Munich

Privacy policy: Datenschutz-Hinweis | EQS Group

The service provider uses the information from the newsletter registration to send and statistically evaluate the newsletters on our behalf. For the evaluation, the sent e-mails contain so-called web beacons or tracking pixels, which are single-pixel image files stored on our website. This makes it possible to determine whether a newsletter message has been opened and which links, if any, have been clicked on. With the help of so-called conversion tracking, it can also be analyzed whether a predefined action (e.g. purchase of a product on our website) has taken place after clicking on the link in the newsletter. In addition, technical information is collected (e.g. time of retrieval, IP address, browser type and operating system). The data is collected exclusively pseudonymously and is not linked to your other personal data, a direct personal reference is excluded. This data is used exclusively for the statistical analysis of newsletter campaigns. The results of these analyses can be used to better adapt future newsletters to the interests of the recipients. The legal basis for this data processing is your granted consent pursuant to Art. 6 (1) lit. a DSGVO, which you give in the course of newsletter registration.

If you wish to revoke your consent to data analysis for statistical evaluation purposes, you must unsubscribe from the newsletter.


Google Analytics

Our website uses Google Analytics, an internet analysis service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland (“Google”). Google Analytics uses so-called “cookies”.

Google will use this information on behalf of the operator of this website for the purpose of evaluating your use of the website, and compiling reports on website activity. Google will also use this information to provide the website operator with other services related to the use of the website and the internet. The IP address sent by your browser as part of Google Analytics will not be combined with any other data held by Google. The processing is carried out in accordance with Art. 6 para. 1 lit. a DSGVO on the basis of the consent given by you.

We use Google Analytics only with activated IP anonymization. This means that your IP address is only processed by Google in a shortened form.

We have concluded an order processing contract with the service provider, in which we oblige him to protect the data of our customers and not to pass them on to third parties.


Since a transfer of personal data to the USA takes place, further protection mechanisms are required to ensure the level of data protection of the GDPR. To ensure this, we have agreed standard data protection clauses with the provider in accordance with Art. 46 (2) lit. c DSGVO. These oblige the recipient of the data in the USA to process the data in accordance with the level of protection in Europe. In cases where this cannot be ensured by this contractual extension, we endeavour to obtain additional regulations and commitments from the recipient in the USA.


The Google Analytics terms of use and information on data protection can be accessed via the following links:

The data is deleted as soon as it is no longer required to achieve the purpose for which it was collected. Deletion of data at user and event level linked to cookies, user IDs (e.g. User ID) and advertising IDs (e.g. DoubleClick cookies, Android advertising ID, IDFA [Apple identifier for advertisers]) takes place no later than 14 months after their collection.

You can prevent cookies from being saved by adjusting the settings of your browser software accordingly. However, we would like to point out that in this case you may not be able to use all functions of this website without restrictions. You can also prevent Google from collecting the data generated by the cookie and from analysing your use of the website (including your IP address) and from processing this data by Google by downloading and installing the browser plug-in available at
